Use of specific open-chain ether isocyanates

2:

• The process as claimed in claim 1, characterized in that the at least one open-chain, optionally branched, ether isocyanate has an NCO functionality of 2 and 2 or 3 carbon atoms are located at least between one of the two NCO groups and the at least one ether oxygen atom.

3:

• The process as claimed in claim 1, characterized in that at least one further coreactant selected from the group consisting of alcohols, amines, water, CO2 and further isocyanates having an NCO functionality≥1 that do not contain an ether group is present.

4:

• The process as claimed in claim 1, characterized in that between 1% and 99% by weight, based on the total amount of compounds that have NCO groups, of the at least one open-chain, optionally branched, ether isocyanate is used, the balance to 100% consisting of one or more further isocyanates having an NCO functionality≥1.

5:

• The process as claimed in claim 4, characterized in that the amount of the at least one open-chain, optionally branched, ether isocyanate is between 50% and 90% by weight.

6:

• The process as claimed in claim 1, characterized in that modified isocyanates having a urethane, urea, biuret, dimer, isocyanurate, iminooxadiazinedione and/or carbodiimide structure are produced from the at least one open-chain, optionally branched, ether isocyanate.

7:

• A process for modifying isocyanates, comprising the reaction of at least one open-chain, optionally branched, ether isocyanate having an NCO functionality≥1, in which 2 or 3 carbon atoms are located between at least one NCO group and at least one ether oxygen atom, optionally in the presence of further coreactants selected from the group consisting of alcohols, amines, water, CO2, and further isocyanates having an NCO functionality≥1.

8:

• A modified isocyanate produced by the process as claimed in claim 7.

9:

• A two-component system containing a component A), comprising at least one modified isocyanate based on an open-chain, optionally branched, ether isocyanate having an NCO functionality≥1, in which 2 or 3 carbon atoms are located between at least one NCO group and at least one ether oxygen atom, and a component B), comprising at least one NCO-reactive compound.

10:

• The two-component system as claimed in claim 9, wherein the at least one NCO-reactive compound is a polyhydroxy compound, selected from the group consisting of a polyether polyol, a polyester polyol, a polycarbonate polyol, and a polyacrylate polyol.

11:

• A one-component system comprising at least one modified isocyanate based on an open-chain produced according to claim 1, optionally branched, ether isocyanate having an NCO functionality≥1, in which 2 or 3 carbon atoms are located between at least one NCO group and at least one ether oxygen atom, the free NCO groups of which have been deactivated with one or more blocking agents.

12:

• A shaped body or coating obtainable or produced by curing a two-component system as claimed in claim 9, optionally under the action of heat and/or in the presence of a catalyst.

13:

• A composite component comprising a material joined at least to a shaped body or a coating as claimed in claim 12 at least in part.
